In general, we know two types of isolation: Channel-to-channel isolation means that the noise or crosstalk between and among all channels is prevented. Input-to-output isolation means that whatever the sensor or measuring wire is connected to in the outside world is isolated from the DAQ ...
Signal from resistor R3 travels down the wire to tube V1A's grid (pin 2) then out the plate to coupling capacitor C1. Tube V1 is split into two identical halves, A & B.After going through grid stopper resistor R3 the audio signal flows down the wire to the preamp tube's control ...
In fact, you can easily create your own intercom system using two telephones, a 9-volt battery (or some other simple power supply) and a 300-ohm resistor that you can get for cheap. You can wire it up like this: Your connection to the phone company consists of two copper wires. ...
To understand the problem, it is helpful to understand something about voltage. Voltage is a measure of a difference in electric potential energy. Electric current travels from point to point because there is a greater electric potential energy on one end of the wire than there is on the other...
Wires can connect two terminals together, or they can connect dozens. When a wire splits into two directions, it creates ajunction. We represent junctions on schematics withnodes, little dots placed at the intersection of the wires. Nodes give us a way to say that "wires crossing this junct...

Class D amplifiers, first proposed in 1958, have become increasingly popular in recent years. What are Class D amplifiers? How do they compare with other kinds of amplifiers? Why is Class D of interest for audio? What is needed to make a “good” audio Class D amplifier? What are the ...
The wire that runs through the speaker system connects to two hook-up jacks on the driver. When the electrical current flowing through the voice coil changes direction, the coil's polar orientation reverses. The voice coil is a basic electromagnet. If you've read How Electromagnets Work, the...
Power supplies One way for noise to sneak into your measurement is through the power supply. This includes both the power supply for the LDO and the power supply for any amplifiers used to gain up the LDO's output. If available, use batteries to power both the LDO and any gain circuitry...
